Assembloids have emerged as a powerful tool for studying previously inaccessible processes of development and tissue homeostasis. While initial #assembloids were developed to model human brain development, there are now models for most organ systems, from the bladder to the heart and gastrointestinal system. In our new article in @CellStemCell, we summarize recent advances in the generation and application of neural and non-neural assembloids to explore complex cell-cell interactions.
